INVENTOR A TTORNE Y FREDERICK K. BUTLER, 0F SEATTLE, WASHINGTON.

ERASER.

Specification of Letters latent.

Patented Jan. 14, 1919.

Application filed January 11, 1917. Serial No. 141,728.

To all whom it may concern:

Be it known that I, FREDERICK K. BUTLER, a citizen of the United States, and a resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Erasers, of which the following is a full, true, and exact specification.

My invention relates to erasers and has for its principal object to provide an improved and novel type of combination abrasive and steel eraser for use in connection with lead pencils and the like. Another object of my device is to provide an eraser means in connection with the end of a lead pencil which engages the inside of the pocket in such a way as to prevent the lead pencil from accidentally dropping from the pocket.

Other objects will appear as my invention is more fully explained in the following specifications, illustrated in the accompanying drawings and pointed out in the appended claim.

Many lead pencils are accidentally lost by dropping from the pocket as they are not in any way retained within the pocket. My device combines the utility of an eraser with means for retaining the pencil within the pocket.

In the drawings, Figure l is a plan view of my device, Fig. 2 is a side elevation of same with parts broken away.

Referring more particularly to the drawings, numeral 1 indicates a lead pencil at the top of Which is removably secured ferrule 2, which is provided with a vertical slit 3 along one side thereof. A mushroom shaped eraser 4 is secured to the ferrule adjacent its upper end. The pencil is cut away as at 5, directly beneath the slot 3 in order to provide a space for an erasing steel 6, which is slidably mounted within the ferrule. The upper end of the steel 6 is sharpened and may be used as a steel eraser, while the lower end is upturned and extends slightly beyond the slit 3 as at 7. The steel eraser is extended beyond the end of the pencil by moving forward within the slit 3 and is similarly withdrawn.

It will be noted that my eraser is of a circular type and is provided with a sharp abrasive edge. When the pencil is placed in the pocket with the eraser end downward, the eraser will engage the lining of the pocket, thereby preventing the accidental loss of the pencil.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readily suggest to others skilled in the art without departing from the spirit and scope of the invention, and I therefore desire to avoid being limited to the exact form shown and described.

Having described my invention, what I claim as new and desire to protect by Let ters Patent, is:

In a. device of the class described the combination of a cylindrical ferrule removably secured to the head end of a lead pencil, a longitudinal slot in said ferrule extending from near its inner end toward the outer end, a mushroom shaped abrasive rubber eraser having a central and cylindrical hole therethrough, whereby the eraser fits tightly over the outer end of the said ferrule, a groove in the outer periphery of the pencil directly beneath the slot in the ferrule, a steel eraser slidably mounted within the said groove and an upturned inner end extending through the slot in the ferrule, whereby the steel eraser may be extended beyond the outer end of the ferrule.
